LANGLEY AIR FORCE BASE, Va. -- Maj. Jason Morvant, chief of surgery at the 1st Fighter Wing Hospital, examines mammogram films. Annual mammograms are key in helping doctors detect and diagnose breast cancer in patients. Both annual mammograms and monthly self-breast examinations play important roles in prevention and early detection of the disease. (U.S. Air Force photo/Airman 1st Class Sylvia Olson)
